About SVET Light Bulb
Dubbed “the health-friendly light bulb,” SVET Light Bulb isn’t just safe for your eyes; its lighting can also improve the quality of your sleep, help you wake up refreshed and alert, allow you to relax when needed, improve your reading and learning, and more. Or, as SVET’s manufacturer puts it, the bulb can help “optimize your physical and mental performance.”
SVET Light Bulb accomplishes this by emitting a full spectrum of high quality light, which mimics natural light output. This way, you’ll get “the right light at the right time”—and the whole process is as easy as replacing a light bulb.
There’s no doubt that light plays an integral role in our life. But can the right light really boost your mental and physical performance? Even if it can, is SVET your best option, or something else altogether? We’ll explore all of this here.
Let’s begin with SVET Light Bulb’s specifications.
The Technical Side Of SVET Light Bulb
SVET Light Bulb’s Specifications
The SVET Light Bulb is about 5” tall and 3.75” wide, and fits standard light bulb sockets. Its high-efficiency LEDs put out about 1,000 lumens (equivalent to an 85W incandescent bulb), with color temperature ranging between 1,800K and 8,000K. In a nutshell, this mimics the full spectrum of light; specifically sunlight.
Using SVET’s iOS or Android apps, you’ll be able to communicate with your Light Bulb via Bluetooth LE and control its color temperature, brightness level, predefined scenario (a set of actions, such as changing brightness and color temp at preset times), and schedule wakeup and sleep times. If you already have a home automation system in place, SVET is also ZigBee Light Link compatible.
Compared to traditional bulbs, SVET Light Bulb lasts up to 10X longer and features a 5-year lifespan, based on 8 hours of usage per day. However, SVET can’t be used outdoors or in bathrooms or other damp, humid locations.
How SVET Works
According to the company, light can affect our physical and mental health from three different aspects:
- Vision: Visual comfort
- Emotion: Aesthetics, comfort, and wellbeing
- Physiology: Circadian rhythm (we’ll come back to this in a second), tiredness, and performance
In order to maximize these aspects on-demand, SVET closely replicates the properties and dynamics of natural light, so that you’re able to “keep you body clock in check.”
How? By adjusting brightness and hue (including intensity, distribution, and spectral composition). You’ll have warm dawn-like light for waking up (called a “sunlight alarm clock”), bluefish light for alertness and performance, warm white light to improve mood, and low-intensity reddish light (called “sunset lighting”) to promote relaxation.
On top of these benefits, SVET’s full spectrum lighting will help you see surrounding colors with minimal distortions, which can be easier on your eyes. This might also “create an ideal reading atmosphere” to “achieve better results” (presumably for learning and comprehension). SVET might even be effective for addressing seasonal affective disorder (SAD)!
SVET can be controlled manually from your iOS or Android app, or you can select one of the presets for different activities, such as maximizing performance, boosting comfort, or promoting relaxation.
That’s certainly a lot of features, but how much will all of this cost you?
What is the SVET Light Bulb’s Price?
As of the time of this writing, SVET wasn’t set to go on sale until April 2015, with an estimated shipping date sometime in the Fall. There also weren’t any prices listed on the SVET website, although we learned through their Facebook page that they’ll cost $80 during their crowdfunding campaign, and $100 thereafter.
While this is expensive, SVET claims their Light Bulbs can save you up to 90% compared to traditional lighting sources.
Once they’ve shipped, all SVET Light Bulbs will come with a 2-year warranty against defects in materials or workmanship.
There wasn’t any refund information listed, so we emailed customer service at email@example.com and received a quick reply. Here’s what we were told:
“We are working on the return policy right now. The terms will vary depending on the country (the US, Canada, the UK, etc.). We will publish the terms once we start accepting preorders.”
Now that we’ve peeled back some of the layers of SVET’s Light Bulb, let’s switch gears for a moment and dive in to some of their key claims.
Can SVET Really Boost Your Physical & Mental Performance?
Briefly, here’s how the company summarizes the basis for their claims (they also provided an accompanying diagram in their Tech Sheet, which we’ve included below):
“A number of studies have shown that exposure to blue-heavy lighting promotes alertness, increases energy and enhances overall performance. Basically, a light with an increased blue light spectrum helps concentrate better, which is a desirable effect for a work environment. At the same time, a light completely devoid of blue, or at least with a much lower amount of it, may be used to achieve better results when we do not need alertness and increased energy. Having the ability to tune lighting at will gives you more control over your productivity and recreation.”
But is this really the case, or is SVET making a mountain out of a molehill?
According to SVET, different light spectrums (or colors) can affect your mood, sleep, and mental performance.
How Color Affects Behavior
Here, SVET’s manufacturer is referencing something known as color psychology. Although it has a complicated name, it basically just references how color can make humans think, feel, or act differently.
A couple admittedly simplistic examples are pink (which would make most people immediately think of females) and blue (which most people would associate with males). But it goes much further than this, since the basic tenets of color psychology indicate that color can affect everything from our buying decisions and sports performance, to time perception and meaning (e.g. red might be associated with power, while purple could be associated with sophistication).
Here’s the catch: Much of the research surrounding color psychology is mixed. So, while people would probably tell you that being in a yellow room makes them feel more energized than a brown room, or that working in natural light makes them more productive than working in a windowless office, many of the claims behind color psychology are anything but proven.
The Circadian Rhythm Connection
Every creature (including plants and microscopic organisms) has what’s known as a circadian rhythm—commonly known as a biological clock—which is defined as “physical, mental and behavioral changes that follow a roughly 24-hour cycle, responding primarily to light and darkness in an organism's environment.” As you can see, it’s very similar to color psychology, but instead of hues it references light, and it also follows a cyclical pattern.
Among many other things, this master clock is responsible for releasing melatonin when it’s time to starting winding down for bed. How? Once light levels drop, melatonin levels increase, making you drowsy. Then, as light levels increase, your body decreases melatonin production so you’re able to wake feeling rested.
Why do we bring this up? Because based on our research and the available evidence, we think SVET Light Bulb will be most effective for perking you up or calming you down. In other words, while it’s certainly possible (and clinically supported in some instances) that full spectrum lights like SVET could boost your mental performance, improve your reading and learning, and more, we think any edge you achieve in these areas would be minimal.
Speaking of which, is there anything else available like the SVET Light Bulb? We’ll address this next as we wrap things up.
Is SVET Light Bulb the Answer?
Given everything we’ve talked about, should you preorder SVET once it becomes available? When it comes down to it, this is wholly up to you. But we think there are some important things to consider before you do.
Does SVET Have Any Competition?
First, understand that if you’re in the market for a full spectrum light bulb (one that mimics natural light), you can find these for sale all over the internet for as little as $3. They’re even so popular that you’ll probably be able to find a decent selection at a couple big box stores nearby.
Sure, these bulbs won’t be able to change their color spectrum or connect to your smartphone, but if your main goal is to obtain natural light in an unnatural environment (such as an office), they might provide the most bang for your buck.
Also, although SVET’s bulbs might last up to 10X longer than traditional bulbs, as the company claims, this is generally the case for most LED light bulbs, and not SVET in particular.
How Many SVET Light Bulbs Will You Need?
Speaking of offices; if you need natural light in a relatively small space, one SVET Light Bulb might suffice. But if you want to improve the light in a larger regularly used area, such as a kitchen or living room, you might have to purchase multiple units. So, be sure to factor this into your budget—and your expectations.
1 SVET = 1 App?
If you did have multiple SVET bulbs around the house, one thing that’s not made clear on their website is whether or not you can control more than one from the same app. Also, we’re not sure how many apps can be assigned to each bulb (one for each member of your household, for example).
The Wild West Of Crowdfunding
Finally (but certainly not least important), remember that SVET isn’t set to go on sale until April 2015, and isn’t expected to ship until the Fall.
In the past, the HighYa team has reviewed several products (such as Coin Credit Card, Vessyl, and TrackR) that looked promising pre-production, but based on customer reviews, might’ve failed to live up to expectations once they made their way to market. Certainly, we’re not saying this will be the case with the SVET Light Bulb; only that, as with any new company, things rarely go exactly as planned, so it’s not unheard of to experience delays.
Will SVET Light Bulb Help You See the Light?
We’ve covered a lot of ground in this review, but here’s what we think it comes down to: If you’re looking to spend the least amount of money to infuse an area with natural light, the SVET Light Bulb probably won’t be your first choice. On the other hand, if you need natural light and you’re passionate about trying out new home automation-related technology, then it could very well be worth rolling the dice.
